Sputum collecting device

Abstract

A sputum collecting device includes a bag attached to a cover and disposed in a container for receiving and collecting a sputum and for forming a peripheral space between the container and the bag, the cover includes an inlet for guiding the sputum from a patient into the bag and includes a tubular member communicative with the container and the peripheral space that is formed between the container and the bag, and a vacuuming source for drawing the air in the bag and the peripheral space that is formed between the container and the bag, and for drawing the sputum through the inlet of the cover and into the bag, and then for collecting the sputum in the bag.

1 . A sputum collecting device comprising:
 a container including a chamber formed therein, and including an upper portion and a lower portion,   a cover attached onto said upper portion of said container,   a bag attached to said cover and disposed in said chamber of said container for receiving and collecting a sputum and for forming a peripheral space between said container and said bag,   said cover including an inlet communicative with said bag for guiding the sputum from a patient into said bag, and including a tubular member communicative with said chamber of said container and said peripheral space that is formed between said container and said bag, and   a vacuuming source for drawing the air in said bag and said peripheral space that is formed between said container and said bag, and for drawing the sputum through said inlet of said cover and into said bag.   
     
     
         2 . The sputum collecting device as claimed in  claim 1 , wherein said cover includes a check valve attached to said inlet of said cover for limiting the sputum to flow into said bag only and for preventing the sputum from flowing out through said inlet of said cover. 
     
     
         3 . The sputum collecting device as claimed in  claim 1 , wherein said cover includes a filter device attached to said tubular member and disposed in said chamber of said container and disposed in said bag. 
     
     
         4 . The sputum collecting device as claimed in  claim 1 , wherein said cover includes a mouth formed therein. 
     
     
         5 . The sputum collecting device as claimed in  claim 4 , wherein said cover includes a lid detachably attached to said mouth of said cover. 
     
     
         6 . The sputum collecting device as claimed in  claim 1 , wherein said container includes an outlet device communicative with said peripheral space that is formed between said container and said bag and coupled to said vacuuming source. 
     
     
         7 . The sputum collecting device as claimed in  claim 6 , wherein said outlet device includes an outlet port coupled to said vacuuming source. 
     
     
         8 . The sputum collecting device as claimed in  claim 6 , wherein said outlet device includes a fastener engaged through said container for securing said outlet device to said container. 
     
     
         9 . The sputum collecting device as claimed in  claim 8 , wherein said outlet device includes a conduit formed therein, and said fastener includes a bore formed therein for communicating said conduit of said outlet device with said peripheral space that is formed between said container and said bag. 
     
     
         10 . The sputum collecting device as claimed in  claim 9 , wherein said fastener includes a head disposed and located in said peripheral space and engaged between said container and said bag for spacing said bag from said container.
